Wikipedia Abstract

Pterygoplichthys multiradiatus is one of several tropical fish commonly known as plecostomus (or plecos). It belongs to the armored catfish family (Loricariidae). Named for its sail-like dorsal fin, the part of its scientific name multiradiatus means "many-rayed" and refers to the rays of the dorsal fin. P. multiradiatus is one of a number of species commonly referred to as the common pleco by aquarists. P. multiradiatus browses on substrate, mainly feeding on benthic algae and aquatic weeds, but will also take worms, insect larvae and other bottom-dwelling invertebrates as food.
